display angle problem

I'd like to make screen rotate with player. I made like this:

1. I made layout 1 width and height to 2000

2. In the center od Iayout I made sprite and gave it 8 direction behavior and checked 'center view on me'.

3. I made some backgrounds around this sprite

4. EVENTS:

Always: sprite: Set angle towards (MouseX, MouseY)

Always: System: Set display angle to sprite.Angle

When I run the game screen goes crazy. Why it's happening, how can I fix that?

MouseX and MouseY return the mouse in layout coordinates taking in to account the display zoom and angle. So if you change the display angle you change the values MouseX and MouseY return which in turn changes the display angle... and you get a strange feedback loop that probably involves the screen spinning really fast.

To fix this add a new layer called "Coordinates" or something. Never scale or rotate this layer - it's just for getting coordinates. MouseX("Coordinates") and MouseY("Coordinates") will then return the unzoomed, unscaled mouse coordinates, and you can use these to set the display angle for other layers (not the whole display, otherwise it'll still affect the Coordinates layer). Hope that helps.

By the way, it often helps to have "Unbounded scrolling" enabled for rotating screens.

Thanks, it helped with the "crazyness" of the screen.

But there is new problem. While turning around (layer is turning with sprite of courese) tiledBackgrounds disappears when layer is on different angles.

Any ideas? anybody? Is it a bug, or am I doing something wrong?

I'm not sure. Posting a .cap file might help.

Hmm, looks like a bug... I guess you could work around it for now by using sprites - post it on the tracker and I'll get round to it soon.
